3 `Claims.

'Ihe primary object of this invention resides in the provision of anattachment for gas burners, adapted to raise the combustibility of thegas and reduce the consumption thereof to the minimum.

Another object of this invention resides in the provision of anattachment for gas burners of such construction that gas, upon beingejected therebeneath, will be intermingled with air and be dischargedtherefrom in a high state of combustibility.

A further object of this invention resides'in the provision of anattachment for gas burners of such construction that gas will passdirectly through certain orifices thereof and indirectly through certainother orices thereof.

A still further object of this invention resides in the provision of anattachment for gas burners adapted to permit a greater discharge ofmixed gas at certain points than at other points thereof.

In addition to the foregoing objects, this invention resides in anattachment forgas burners of such construction that gas ejectedtherebeneath will encounter baffles adapted to disintegrate the streamof gas and permit air to commingle therewith before discharging the gas,so mixed, through exit orifices.

I Aside from the aforesaid objects this invention resides in theprovision of an attachment for gas burners adapted to not onlydisintegrate the stream of gas ejected therebeneath, but to direct aircurrents into the gas, so as to createa high state of combustibility atthe point of utilization.

With theseand other objects in View, `this invention resides in certainnovel features of construction and arrangement of elements to be moreparticularly set forth in the specification, illustrated in theaccompanying drawing and pointed out in the appended claims and, whilethe disclosure depicts my present conception of the invention, the rightis reserved to make such changes in construction as come within thescope of the claims. I

In the accompanying drawing forming a part of this application:

Fig. 1 is a side view of a gas burner with which is associated anattachment constructed in accordance with this invention.

Fig. 2 is a plan view of the attachment.

Fig. 3 is a bottom plan view thereof.

Fig. 4 is an enlarged sectional View on line 4-4 of Fig. 2.

In the present embodiment of this invention the numeral 5 designates agas burner of the conventional type with which is associated an at- (Cl.15S- 113) tachment lll forming the subject matter of this application.

The aforesaid attachment I8 is preferably formed of cast iron or othersuitable material of concavo-convex configuration and is adapted to restupon the burner 5 through the instrumentality of feet I2 which disposesthe periphery I4 of the attachment I0in spaced relation to the burner toprovide air inlet passages I6.

Disposed approximately at the lapex or center of the attachment is anorice I8 while disposed adjacent the feet I2 are orifices 20 of lesserdiameter than the orifice I8.

Surrounding each orifice 20 on three sides and extending toward theorifice I8 are bafiies 22 which are of substantially U shape, the outerends of the limbs of each baflie being connected to a part of the innerface of a foot l2, so that each orifice 20 is surrounded by four Walls.These baffles are adapted to defiect gas from the burner 5 as it fiowstoward the orifices 20 and, through the provision of the air `passagesI6 between the feet I2, the stream of gas, so defiected anddisintegrated, is mixed with air prior to passing through the orificesI8, 20 and other orifices 24 which are of a diameter smaller than theaforesaid orifices 20.

The latter orifices 24 are preferably disposed adjacent the baffles 22in direct communication with the air passage I6 and concentricallydisposed inwardly of the orifices 20 and outwardly of the orifice I8.

With an attachment constructed as aforesaid, it is apparent that thestream of gas ejected therebeneath will be properly disintegrated by thebaffles 22 whereupon air entering the passages lli` will commingletherewith and, through the provision of variable sized orificesassociated with baies arranged as set forth, the gas is not only I mixedto a high state of combustibility but is governed in its excursionthrough the orifices.

Having thus fully described this invention what I claim and desire toprotect by Letters Patent is: 1. An attachment for gas burnerscomprising a substantially inverted saucer shaped member having legsdepending from its periphery and having orifices therein, and bafliesdepending from its under surface, each bafiie having parts connected toa leg to form an enclosure, one of certain of said orifices being withineach enclosure.

` 2. An attachment for a gas burner comprising a concave-convex` memberhaving spaced feet depending from its periphery, substantially U shapedbaflies depending from the under face of the member, each bae havinglthe 'ends of its limbs connected with a part of the inner face of a footand said member having orices therein certain of which open out into thespaces formed by the baies and the feet.

3. An attachment for a gas burner comprising a concavo-convex memberhaving spaced feet depending from its periphery, substantially U- shapedbafes depending from the under face of 10 the member, each baiie havingthe ends of its limbs connected with a part of the inner face of a footand said member having orifices therein certain of which open out intothe spaces formed by the baffles and the feet, said orifices being ofdifferent sizes, a large orifice being located at the center of themember, intermediate size orifices opening out into said spaces andsmall orices being located between the inner ends of the baffles.
